Component Scale - Set Z as X&Y Scales

[Lersince1991]

Hi,

I have a site plan that someone else has drawn and they have scaled all the trees disproportionately, i.e. they have only scaled the x and y but left the z as 1, so when imported into 3D, all the trees are the same height... some skinny and some fat.

now theres hundreds of trees, how can I set the z scale as the x (or Y) scales so make them proportionate again please?

Have the tree component-instances [blocks] been scaled or is it the contents of the component-definition itself ?
Is the scaling consistent ?
How would establish each Z height relative to its XY ?
etc etc...
So much to consider

[Lersince1991]

so in autocad the blocks were scaled at for example;

x-5
y-5 (same as x)
z-1

the z would need to be the same as the x or y to be proportionate again.
They are just the components, nothing to do with contents.
the scaling of each is different for each size tree, for example;

tree 1
x-3, y-3, z-1

tree 2
x-8, y-8, z-1

where as it should be
tree 1
x-3, y-3, z-3

tree 2
x-8, y-8, z-8

This one liner copy+pasted into the Ruby Console + <enter> affects ALL component-instances in the model.
It assumes the X/Y is scaled the same amount.
It applies that scale-factor to the Z too.
It is one step undo-able.

m=Sketchup.active_model;m.start_operation('!');m.definitions.each{|d|next if d.group? || d.image?; d.instances.each{|i|t=i.transformation;f=t.xscale;i.transform!(Geom;;Transformation.scaling(t.origin,f/t.xscale,f/t.yscale,f/t.zscale,))}};m.commit_operation;

This alternative version only processes component-instances in the current Selection.

m=Sketchup.active_model;m.start_operation('!');m.selection.grep(Sketchup;;ComponentInstance).each{|i|t=i.transformation;f=t.xscale;i.transform!(Geom;;Transformation.scaling(t.origin,f/t.xscale,f/t.yscale,f/t.zscale,))};m.commit_operation;

Perfect Thanks! Needed this so many times as there are a lot of idiots that scale oddly in AutoCAD

Cheers TIG!
